• Should I build a multi-threaded system that handles events from a game and sorts them, independently, into different threads based on priority?

  - by JonathonG

  Can I build a multi-threaded system that handles events from a game and sorts them, independently, into different threads based on priority, and is it a good idea? Here's more info: I am about to begin work on porting a mid-sized game from Flash/AS3 to Java so that I can continue development with multi-threading capabilities. Here's a small bit of background about the game: The game contains numerous asynchronous activities, such as "world updating" (the game environment is constantly changing based on a set of natural laws and forces), procedural generation of terrain, NPCs, quests, items, etc., and on top of that, the effects of all of the player's interactions with his environment are programmatically calculated in real time, based on a set of constantly changing "stats" and once again, natural laws and forces. All of these things going on at once, in an asynchronous manner, seem to lend themselves to multi-threading very well. My question is: Can I build some kind of central engine that handles the "stacking" of all of these events as they are triggered, and dynamically sorts them out amongst the available threads, and would it be a good idea? As an example: Essentially, every time something happens (IE, a magic missile being generated by a spell, or a bunch of plants need to grow to their next stage), instead of just processing that task right then and adding the new object(s) to a list of managed objects, send a reference to that event to a core "event handler" that throws it into a stack of all other currently queued events, which then sorts them out and orders them according to urgency, splits them between a number of available threads for as-fast-as-possible multithreaded execution.

• Thoughts on exception handling.

  - by AndyScott

  Was working on a windows form app (something I haven't done in a while), adding threading and logging so that it would work a little more smoothly and have a record of who did what.  I was just about at the point where I was going to check it into source control when I noticed that the Output window was showing "A first chance exception of type 'System.InvalidCastException' occurred in mscorlib.dll", so I googled it.  In reading some threads about the error, I came across the following comment and it got me thinking: "In addition, while they should be avoided if possible, exceptions are a quite legitimate part of program execution. It's their going unhandled that is a real issue, because that means crashy, crashy." How do you normally use exception handling?  I feel that exceptions are intended to handle errors in code (in my experience generally related to bad data making its way into the system).  Now don't get me wrong, I understand that exceptions happen and should be dealt with, but I feel that they are a "last resort" to keep a program from crashing, but should never be a way to pass data or continue logical processing that could be handled in standard code flow. I mention this, because I have seen it done. What do you think?

• Is using a dedicated thread just for sending gpu commands a good idea?

  - by tigrou

  The most basic game loop is like this : while(1) { update(); draw(); swapbuffers(); } This is very simple but have a problem : some drawing commands can be blocking and cpu will wait while he could do other things (like processing next update() call). Another possible solution i have in mind would be to use two threads : one for updating and preparing commands to be sent to gpu, and one for sending these commands to the gpu : //first thread while(1) { update(); render(); // use gamestate to generate all needed triangles and commands for gpu // put them in a buffer, no command is send to gpu // two buffers will be used, see below pulse(); //signal the other thread data is ready } //second thread while(1) { wait(); // wait for second thread for data to come send_data_togpu(); // send prepared commands from buffer to graphic card swapbuffers(); } also : two buffers would be used, so one buffer could be filled with gpu commands while the other would be processed by gpu. Do you thing such a solution would be effective ? What would be advantages and disadvantages of such a solution (especially against a simpler solution (eg : single threaded with triple buffering enabled) ?

• What is the simplest way to render video into memory (for drawing to a texture) in .NET?

  - by sebf

  In my project I would like to be able to play back video on surfaces in the world. I intend to do this by having the video frames rendered to a block of memory, then use this to update a texture each frame. Everything is in place - except for the part that actually gets the video. I have looked on Google and found that the video library world is very expansive (and geared towards video processing), and am having trouble finding a suitable one. FFMpeg is very comprehensive, but is an entire suite and would take a good amount of work to integrate. So far the most promising library I've found is the one based on the VLC player libraries - by virtue of it using the same resources as VLC Player it is known to be very capable; it also renders to blocks of memory, but the API (at least of the one on Codeplex) is more of a port of the C++ API rather than a managed wrapper. The 'solution' can be any wrapper/API/library, but with characteristics that make it suitable for use in a rendering engine, namely: Renders the video frame data to memory, so it can be picked up and passed to a texture on the GPU easily. Super simple - all that is needed is a way to load, jump and render a frame programatically - ideally it would use the systems codecs and not require an assortment of plugins. Permissive license (LGPL or more free-er) .NET bindings at least; all the better if it is natively managed Can anyone suggest a lightweight, (.NET) library, that can take a video file, and spit out some frames into a byte[]?

• How did we get saddled with the (hierarchical) filesystem as the basic data structure?

  - by user1936

  I'm self-taught and I don't have a CS degree. The more I've been learning about data structure, the more I wonder, in this day and age, how are we still saddled with the filesystem, with directories and files, as the basic data storage structure on the OS? I understand the simplicity of it, but it seems nowadays that there could be more options available natively. As far as I'm aware, the only project to improve the basic functionality of the filesystem was ReiserFS, where you could tell what line of a file was changed by whom, and when. For instance, if I could have native tagging for files, where I could tag images, diagrams, word-processing documents, an entire code repository, all as belonging to a single project, that would really be helpful to me. Since I'm stuck in the filesystem paradigm, I know that I could put all those into a single folder/directory, but what if they already exist in disparate directories, and they need to stay there? I know there are programs out there that can do this, but why aren't they on the filesystem? Something that would be nice to have is some kind of relational feature in the filesystem, like you get with RDBMSes. I understand that that was supposed to be part of Vista/7, but that fell off the feature list too. Sure, any program can store a binary file and have any data structure it wants in it, by why couldn't the OS offer more complex ways of storing data, beyond the simple heirarchy of the filesystem?

• XNA - Obtaining depth from the scene's render target?

  - by user1423893

  I'm currently rendering my scene to a render target so it can be used for rendering methods such as post processing and order independent transparency. rtScene = new RenderTarget2D( GraphicsDevice, GraphicsDevice.PresentationParameters.BackBufferWidth, GraphicsDevice.PresentationParameters.BackBufferHeight, false, SurfaceFormat.Rgba64, DepthFormat.Depth24Stencil8, // Requires a depth format for objects to be drawn correctly (e.g. wireframe model surrounding model) 0, RenderTargetUsage.PreserveContents ); I am required to use RenderTargetUsage.PreserveContents so that the same render target can be rendered to multiple times, once for each of the draw methods below. DrawBackground DrawDeferred DrawForward DrawTransparent The problem is that DrawTransparent requires a copy of the scene's depth as a texture. Is there any way to obtain this from the scene render target above (rtScene)? I can't have more than one render target with RenderTargetUsage.PreserveContents as this causes problems on hardware such as the XBOX 360, so rendering the depth to a separate render target at the same time as I render the scene isn't possible as far as I can tell. Would I be able to get around this problem by "Ping-Ponging" two render targets (using the more compatible RenderTargetUsage.DiscardContents) and using the result for the depth texture?

• Series On Embedded Development (Part 3) - Runtime Optionality

  - by Darryl Mocek

  What is runtime optionality? Runtime optionality means writing and packaging your code in such a way that all of the features are available at runtime, but aren't loaded and used if the feature isn't used. The code is separate, and you can even remove the code to save persistent storage if you know the feature will not be used. In native programming terms, it's splitting your application into separate shared libraries so you only have to load what you're using, which means it only impacts volatile memory when enabled at runtime. All the functionality is there, but if it's not used at runtime, it's not loaded. A good example of this in Java is JVMTI, Java's Virtual Machine Tool Interface. On smaller, embedded platforms, these libraries may not be there. If the libraries are not there, there's no effect on the runtime as long as you don't try to use the JVMTI features. There is a trade-off between size/performance and flexibility here. Putting code in separate libraries means loading that code will take longer and it will typically take up more persistent space. However, if the code is rarely used, you can save volatile memory by including it in a separate library. You can also use this method in Java by putting rarely-used code into one or more separate JAR's. Loading a JAR and parsing it takes CPU cycles and volatile memory. Putting all of your application's code into a single JAR means more processing for that JAR. Consider putting rarely-used code in a separate library/JAR.

• Looking for a better Factory pattern (Java)

  - by Sam Goldberg

  After doing a rough sketch of a high level object model, I am doing iterative TDD, and letting the other objects emerge as a refactoring of the code (as it increases in complexity). (That whole approach may be a discussion/argument for another day.) In any case, I am at the point where I am looking to refactor code blocks currently in an if-else blocks into separate objects. This is because there is another another value combination which creates new set of logical sub-branches. To be more specific, this is a trading system feature, where buy orders have different behavior than sell orders. Responses to the orders have a numeric indicator field which describes some event that occurred (e.g. fill, cancel). The combination of this numeric indicator field plus whether it is a buy or sell, require different processing buy the code. Creating a family of objects to separate the code for the unique handling each of the combinations of the 2 fields seems like a good choice at this point. The way I would normally do this, is to create some Factory object which when called with the 2 relevant parameters (indicator, buysell), would return the correct subclass of the object. Some times I do this pattern with a map, which allows to look up a live instance (or constructor to use via reflection), and sometimes I just hard code the cases in the Factory class. So - for some reason this feels like not good design (e.g. one object which knows all the subclasses of an interface or parent object), and a bit clumsy. Is there a better pattern for solving this kind of problem? And if this factory method approach makes sense, can anyone suggest a nicer design?

• The latest version of the EJB 3.2 spec available on java.net project

  - by Marina Vatkina

  If you are not following us on the users alias, here is a quick update. Just before JavaOne, I uploaded the latest version of the EJB 3.2 Core document to the ejb-spec.java.net downloads. If you want to see the detailed changes, download it If you are interested in the high-level list, or would like to know what to look for, this is the list of changes since the previous version (found on the same download page): Specified that the SessionContext object in a the singleton session bean is thread-safe Clarified that the EJB timers distribution and failover rules apply only to persistent timers Clarified that non-persistent timers returned by getTimers and getAllTimers methods are from the same JVM as the caller Fixed section numbering (left over after moving it to its own chapter) in Ch 17 Noted that only 3.0 and 3.1 deployment descriptors are required to be supported in EJB 3.2 Lite for prior versions of the applications Fixes for EJB_SPEC-61 (Ambiguity in EJB lite local view support) and EJB_SPEC-59 (Improve references to the component-defining annotations) JMS/MDB changes: added new standard activation properties and the unique identifier, and rearranged sections for easier navigation Fixed unresolved cross-refs Updated the rule: only local asynchronous session bean invocations are supported in EJB 3.2 Lite Synchronized permissions in the Table with the permissions listed for the EJB Components in the Java EE Platform Specification Table EE.6-2 Specified that during processing of the close() method, the embeddable container cancels all pending asynchronous invocations and non-persistent timers Updated most of the referenced documents to their latest versions Happy reading!

• Recommended formats to store bitmaps in memory?

  - by Geotarget

  I'm working with general purpose image rendering, and high-performance image processing, and so I need to know how to store bitmaps in-memory. (24bpp/32bpp, compressed/raw, etc) I'm not working with 3D graphics or DirectX / OpenGL rendering and so I don't need to use graphics card compatible bitmap formats. My questions: What is the "usual" or "normal" way to store bitmaps in memory? (in C++ engines/projects?) How to store bitmaps for high-performance algorithms, such that read/write times are the fastest? (fixed array? with/without padding? 24-bpp or 32-bpp?) How to store bitmaps for applications handling a lot of bitmap data, to minimize memory usage? (JPEG? or a faster [de]compression algorithm?) Some possible methods: Use a fixed packed 24-bpp or 32-bpp int[] array and simply access pixels using pointer access, all pixels are allocated in one continuous memory chunk (could be 1-10 MB) Use a form of "sparse" data storage so each line of the bitmap is allocated separately, reusing more memory and requiring smaller contiguous memory segments Store bitmaps in its compressed form (PNG, JPG, GIF, etc) and unpack only when its needed, reducing the amount of memory used. Delete the unpacked data if its not used for 10 secs.

• design an extendible and pluggable business logic flow handler in php

  - by Broncha

  I am working on a project where I need to allow a pluggable way to inject business processes in the normal data flow. eg There is an ordering system. The standard flow of the application is A consumer orders an item. Pays for it and card is authorized. Admin captures the payment. Order is marked as complete and item is shipped. But this process may vary (extra steps in between) for different clients. Say a client would need to validate the location of the consumer before he is presented with a credit card form, OR his policies might require some other processes in between. I am thinking of using State Pattern for processing orders, saving the current state of the order in database, and initializing the state of order from the saved state. I would also need some mechanism, where a small plugin would be able to inject business specific states in the state machine. Am I thinking the right way? Are there already implemented patterns for this kind of situation? I am working with Codeigniter and basically this would mean for me, to redirect to proper controller according to the current state of the order. Like, if the state of the order is unconfirmed then redirect the user to details page and then change the state to pending. If some client would need to do some validation, then register an intermediate state between unconfirmed and pending Please suggest.

• Welcome!

  - by mannamal

  Welcome to the Oracle Big Data Connectors blog, which will focus on posts related to integrating data on a Hadoop cluster with Oracle Database. In particular the blog will focus on best practices, usage notes, and performance tips for using Oracle Loader for Hadoop and Oracle Direct Connector for HDFS, which are part of Oracle Big Data Connectors. Oracle Big Data Connectors 1.0 also includes Oracle R Connector for Hadoop and Oracle Data Integrator Application Adapters for Hadoop. Oracle Loader for Hadoop: Oracle Loader for Hadoop loads data from Hadoop to Oracle Database. It runs as a MapReduce job on Hadoop to partition, sort, and convert the data into an Oracle-ready format, offloading to Hadoop the processing that is typically done using database CPUs. The data is thenloaded to the database by the Oracle Loader for Hadoop job (online load) or written out as Oracle Data Pump files for load and access later (offline load) with Oracle Direct Connector for HDFS. Oracle Direct Connector for HDFS: Oracle Direct Connector for HDFS is a connector for high speed access of data on HDFS from Oracle Database. With this connector Oracle SQL can be used to directly query data on HDFS. The data can be Oracle Data Pump files generated by Oracle Loader for Hadoop or delimited text files. The connector can also be used to load data into the database using SQL.

• TraceTune supports uploading Zip files

  - by Bill Graziano

  I’ve been using the online version of ClearTrace more and more lately.  When I get to a new client it’s just much easier to upload a trace file rather than install ClearTrace. That means I’ve finally been adding more features to it.  The two latest features are around ease of use. You can now upload a ZIP file that contains a trace file.  Trace files are already somewhat compressed.  Putting it in a ZIP file further compresses it by a factor of 8X or 9X in my testing. That means you can start with a 100MB trace and end up with a 10Mb-12MB ZIP file to upload.  I’m consistently able to get over 150,000 events in a 100MB ZIP file.  That gives me a pretty good look at a system. The second part of this is that files are now processed asynchronously.  After you upload a file you’ll be taken to a processing page that updates every few seconds with the number of rows processed.  It generally takes under a minute to process a 100MB trace file but I *hated* staring at a blank screen. Give TraceTune a try.  It’s getting easier to use every day.

• Multi Threading - How to split the tasks

  - by Motig

  if I have a game engine with the basic 'game engine' components, what is the best way to 'split' the tasks with a multi-threaded approach? Assuming I have the standard components of: Rendering Physics Scripts Networking And a quad-core, I see two ways of multi-threading: Option A ('Vertical'): Using this approach I can allow one core for each component of the engine; e.g. one core for the Rendering task, one for the Physics, etc. Advantages: I do not need to worry about thread-safety within each component I can take advantage of special optimizations provided for single-threaded access (e.g. DirectX offers a flag that can be set to tell it that you will only use single-threading) Option B ('Horizontal'): Using this approach, each task may be split up into 1 <= n <= numCores threads, and executed simultaneously, one after the other. Advantages: Allows for work-sharing, i.e. each thread can take over work still remaining as the others are still processing I can take advantage of libraries that are designed for multi-threading (i.e. ... DirectX) I think, in retrospect, I would pick Option B, but I wanted to hear you guys' thoughts on the matter.

• Globacom and mCentric Deploy BDA and NoSQL Database to analyze network traffic 40x faster

  - by Jean-Pierre Dijcks

  In a fast evolving market, speed is of the essence. mCentric and Globacom leveraged Big Data Appliance, Oracle NoSQL Database to save over 35,000 Call-Processing minutes daily and analyze network traffic 40x faster.  Here are some highlights from the profile: Why Oracle “Oracle Big Data Appliance works well for very large amounts of structured and unstructured data. It is the most agile events-storage system for our collect-it-now and analyze-it-later set of business requirements. Moreover, choosing a prebuilt solution drastically reduced implementation time. We got the big data benefits without needing to assemble and tune a custom-built system, and without the hidden costs required to maintain a large number of servers in our data center. A single support license covers both the hardware and the integrated software, and we have one central point of contact for support,” said Sanjib Roy, CTO, Globacom. Implementation Process It took only five days for Oracle partner mCentric to deploy Oracle Big Data Appliance, perform the software install and configuration, certification, and resiliency testing. The entire process—from site planning to phase-I, go-live—was executed in just over ten weeks, well ahead of the four months allocated to complete the project. Oracle partner mCentric leveraged Oracle Advanced Customer Support Services’ implementation methodology to ensure configurations are tailored for peak performance, all patches are applied, and software and communications are consistently tested using proven methodologies and best practices.

• Complex string matching with fuzzywuzzy

  - by That1Guy

  I'm attempting to write a process that matches obscure strings to a single 'master string' for further processing. I have a lot of data that looks something like this: Basketball Basket Ball Football BasketBallR BBall BBall - r FootB ...and so on. These need to be mapped to a master record like so: Basketball = Basket Ball, BBall Basketball - R = BasketBallR, BBall - r I also have instances of data resembling this format: Football -r FootBall - r-g/H,Q,HH These situations need to be separated into different categories before being mapped. For example FootBall - r-g/H,Q,HH should be: Football - r Football - g Football - H Football - Q Football - HH At this point, it still needs to be mapped to a master record... I've tried several different combinations of fuzzywuzzy matching methods, Levenshtein Distance measurements, regex, etc. and can't seem to find a reliable method to logically associate different naming styles of a single item with a master name. I'm throwing my hands up in desperation. Are there any existing python resources than can help sort out my problem? Are there other options? Can anybody point out an obvious option that I might have overlooked? Basically, any suggestion, solution, resource or alternative method is greatly appreciated.

  Removing the package from cache, and disabling Recommended Updates in Software Sources gives me an error saying I need to install this package. I've tried to update several times, but it keeps hanging on unpacking the ubuntu-sso-client package. Which forces me to hard-reset to unlock the package manager. I've tried: sudo dpkg --configure -a No errors sudo apt-get upgrade --fix-broken Wants me to reinstall said package, resulting in it hanging Removing the package: sudo rm -f /var/cache/apt/archives/ubuntu-sso-client_1.0.8-0ubuntu1_all.deb Results in the same effect, it re-downloads then hangs I can de-select Recommended Updates but I get error messages when I try to update again: E: The package ubuntu-sso-client needs to be reinstalled, but I can't find an archive for it. Which won't let me continue Finally re-enabling the source, I try to remove ubuntu-sso sudo apt-get remove ubuntu-sso-client It removes a bunch of other packages but complains about the package: dpkg: error processing ubuntu-sso-client (--remove): Package is in a very bad inconsistent state - you should reinstall it before attempting a removal. Reinstalling ubuntu-sso-client hangs :( I'm at my wits end, any ideas? I would be nice to install all the other updates but this one is preventing it.

• Solutions for cheaply replacing poorly-supported onboard ATI card with discreet graphics on desktop machine?

  - by echo-flow

  I have put Ubuntu on my mum's desktop computer. Unfortunately, the open source radeon driver does not work well with the onboard ATI graphics, and ATI's proprietary driver no longer supports the hardware at all. In order to use the ATI proprietary driver with this hardware, it is necessary to use an older version of Xorg, which is now only available in versions of Ubuntu older than 8.10. Unfortunately, the open source radeon driver seems to be causing X to lock up intermittently when my mum uses Audacity. I'm willing to accept that some hardware is not well-supported on Ubuntu, and so, because this is a desktop computer with a couple of free PCI slots, I think a better solution might simply be to plug in a new graphics card that might have better driver support, and to disable the onboard ATI card in the BIOS. The requirements for this card are that it be inexpensive and have robust (preferably open source) driver support in Ubuntu 10.04. Heavy-duty graphics processing power is not a requirement. A second-hand card on Ebay would also be fine. Can anyone make some recommendations?

• Do cross reference database tables have a place in domain driven design?

  - by Mike Cellini

  First some background. Let's say we have a system where a customer is placing an order in a web interface. The items that customer is ordering can priced in various ways. Sometimes including the cost of delivery and sometimes not at all. That pricing effectively depends on a variety of factors including the vendor's own pricing model, that vendor's individual contracts with customers as well as that vendor's contracts with its own suppliers. Let's assume that once a customer places an order for a particular item and chooses a contract if any, the method of delivery can be determined by variables on those contracts. Those delivery methods also live in their own table in the database and have various properties consumed downstream. It makes sense that a cross reference or lookup table would store that information. That table would be loaded into the domain and could then be used to apply the appropriate delivery method while processing the order. Does this make sense in the context of domain driven design? Or is my thinking too relational? Is this logic that should be built into it's own class/method (I mean beyond apply the cross reference table data)?

• Web dev/programmer with 4.5 yrs experience. Better for career: self-study or master's degree? [closed]

  - by Anonymous Programmer

  I'm a 28 year-old web developer/programmer with 4.5 years of experience, and I'm looking to jump-start my career. I'm trying to decide between self-study and a 1-year master's program in CS at a top school. I'm currently making 65K in a high cost-of-living area that is NOT a hot spot for technology firms. I code almost exclusively in Ruby/Rails, PHP/CodeIgniter, SQL, and JavaScript. I've slowly gained proficiency with Git. Roughly half the time I am architecting/coding, and half the time I am pounding out HTML/CSS for static brochureware sites. I'd like to make more more money while doing more challenging/interesting work, but I don't know where to start. I have an excellent academic record (math major with many CS credits, 3.9+ GPA), GRE scores, and recommendations, so I am confident that I could be admitted to a great CS master's program. On the other hand, there is the tuition and opportunity cost to consider. I feel like there are a number of practical languages/tools/skills worth knowing that I could teach myself - shell scripting, .NET, Python, Node.js, MongoDB, natural language processing techniques, etc. That said, it's one thing to read about a subject and another thing to have experience with it, which structured coursework provides. So, on to the concrete questions: What programming skills/knowledge should I develop to increase my earning potential and make me competitive for more interesting jobs? Will a master's degree in CS from a top school help me develop the above skills/knowledge, and if so, is it preferable to self-study (possibly for other reasons, e.g., the degree's value as a credential)?

• How do I daemonify my daemon?

  - by jonobacon

  As part of the Ubuntu Accomplishments system I have a daemon that runs as well as a client that connects to it. The daemon is written in Python (using Twisted) and provides a dbus service and a means of processing requests from the clients. Right now the daemon is just a program I run before I run the client and it sets up the dbus service and provides an API that can be used by the clients. I want to transform this into something that can be installed and run as a system service for the user's session (e.g. starting on boot) and providing a means to start and stop it etc. The problem is, I am not sure what I need to do to properly daemonify it so it can run as this service. I wanted to ask if others can provide some guidance. Some things I need to ask: How can I treat it as a service that is run for the current user service (not a system service right now)? How do I ensure I can start, stop, and restart this session service? When packaging this, how do I ensure that it installs it as a service for the user's session and is started on login etc? In responding, if you can point me to specific examples or solutions I need to implement, that would be helpful. :-) Thanks! Jono

• How to control messages to the same port from different emitters?

  - by Alex In Paris

  Scene: A company has many factories X, each emits a message to the same receive port in a Biztalk server Y; if all messages are processed without much delay, each will trigger an outgoing message to another system Z. Problem: Sometimes a factory loses its connection for a half-day or more and, when the connection is reestablished, thousands of messages get emitted. Now, the messages still get processed well by Y (Biztalk can easily handle the load) but system Z can't handle the flood and may lock up and severely delay the processing of all other messages from the other X. What is the solution? Creating multiple receive locations that permits us to pause one X or another would lose us information if the factory isn't smart enough to know whether the message was received or not. What is the basic pattern to apply in Biztalk for this problem? Would some throttling parameters help to limit the flow from any one X? Or are their techniques on the end part of Y which I should use instead ? I would prefer this last one since I can be confident that the message box will remember any failures, which could then be resumed.
